Description
Added place to hold M3 Nut so as to make assembly and removal quicker in case of jams.
OpenSCAD file included. You can also comment out a thin section if you have issues printing this as sometimes the thin frame catches on the print nozzle as it moves back and forth.
Adding the plane back in means the print frame has more support when printing and you just cut away the thin membrane with a blade once printing has completed.
N.B. Original STL from remix included as the OpenSCAD includes the original model as part of the modification.
------------------
An updated version of the orbiter extruder mount to fit the new 2.0 version.

it is also raised to clear the top of the x-carriage so the motor is facing the back.
edited in Fusion 360 from the original STL. the screw holes are a very tight alignment but you can bore them out a bit if your tolerances are off slightly
Had to select Prusa Mk3s because Mini is not an option still
